Present value of bond

Please refer to tab 3-16 to solve and explain.
A 10-year U.S. Treasury bond with a face value of $10,000 pays a coupon of 5.5%
(2.75% of face value every six months). The semiannually compounded interest rate
is 5.2% (a six-month discount rate of 5.2/2 = 2.6%).

a. What is the present value of the bond?
b. Generate a graph or table showing how the bond's present value changes for semiannually
compounded interest rates between 1% and 15%.
